    This was one of my first purchases from this company, the Shipping was very direct and the quality of the product is top notch. Even without their jig I was able to use a universal jig without issue. After I completed one I immediately ordered two more. Can’t say enough about the quality of this product, I will definitely be shopping this sight again.

    A friend and I each bought one of these 80% lowers and milled them out. They arrived in perfect condition. The finish seems quite durable, didn’t mark it up at all during the milling process. This was our first attempt at this and everything turned out perfect.

    I could not be more pleased with this lower. Will surely be buying another once I accumulate all I need for this build.

    The lower looks like a good deal (and it is) just be prepared to wait at least a month for it to ship out . I didn’t know this when I ordered it l.

    I had to leave a review of my shipping experience, after reading the previous review. I ordered 2 of these from Thunder Tactical two days after realizing that an order with another company was on backorder. Within 48 hours of my order I had a tracking number. Total time from purchase to doorstep was less than one calendar week (5 business days). I am very happy with the price and shipping speed. I haven’t milled it out yet, but I’m sure it will be functional.

    I have used these lowers multiple times to make excellent rifles and getting ready to do my first pistol. I cannot say enough about how impressed I am with the quality and service Thunder Guns brings to the table. I’ve done other lowers from big, well known companies with good and bad results but for the price, quality and service, these can’t be beat. For me at least, shipping time was quick and I didn’t have to sweat a back order. Having run my own business I know that things happen that can delay stuff but the communication I’ve received tells me customer service is on the ball. Probably going to make another order soon and I think it might time to try a .308 on for size. Well done folks!

    Excellent lower. Fit perfect with my upper, and you can’t beat this price!

    just received my lower and jig. It arrived in great shape and it only took a week. I’m very happy with it, and will be purchasing from you again

    Received my entire order in around 7 – 10 days as the confirmation email stated. Very pleased with the finish and quality of the 80% lower. This was my first build and I spent a lot of time watching videos. Everything fit well and I could not be happier. Best of all it shoots…. I added a 300 AAC upper and it dropped right in. If you order SKU # 1217 it comes stamped with safe-fire. Forgot to mention that the price is outstanding. Happy building..

    Over time I have ordered several of these as well as many matching uppers and 308 uppers and lowers. To be completely honest thier shipping system is greatly lacking and I personally think they could use some improvement there. However, quality of product and pricing is truly amazing. At last count I have purchased and milled well over a dozen of thier lowers and I have never had a single issue with thier products. I’ve even milled a blem lower of theirs and I never could see why they qualified it as a blem. So, the bottom line is this. Yes they are slow to ship and especially during these times with the virus. But if you’re looking for really good prices and great quality products, look no further. I do with they had billet lowers in the ar15 format. Either way, 5 stars to you. PS. What is up with upper/lower set is $109.99 but if you purchase the upper and lower separately it’s under $90.00 combined. What is up with that????

    I ordered 2, the rear upper lug pocket is ,030 over mil spec. So the upper receiver moves all over the place. It’s not safe. Very poor customer service. I’m disputing the charge with AMX since they won’t take them back. Buyer beware.

    Not the happiest, but they’ll get you by. As customer service goes, overall not pleased. Originally ordered four receivers total, weeks later received my shipment with ONLY one out of four receivers. Took exactly 25 calls for an answer to go through (I have screenshots with time). The gentleman that picked up was kind overall. Said he’ll have the rest shipped out. I added an additional two to my order since they were shipping the rest out. He said as long as I submitted the order online within the next few minutes I could and he’ll refund me the shipping cost and have them sent overnight. A few days later I received my order, but they weren’t sent overnight nor was my additional shipping cost ever refunded (weeks later, still no refund nor a response to my email). I don’t think I’d purchase from this company again considered I had three issues just within a matter of a few days.

    I ordered a 9mm 80% lower. Very nice billet lower everything went together perfect and it is very sold. Ordered 2 regular AR lowers and they great as well with a good price. Now looking at a few kits. I have told a few friends about your lowers. Thanks Thunder Tactical!!!!
